Movek Group mainly installs solar panels with vacuum pipes. Movek Group sells and installs solar panels of Swedish company Sol & Energiteknik SE AB as independent systems as well as connected with heat pump systems. Installed solar panels have shown themselves as efficient equipment in using direct solar energy. Special structure of solar panels of Sol & Energiteknik SE AB gives them high efficiency and due to vacuum pipes the position of panel towards horizon does not depend to bigger extent on the rising angle of sun beams and azimuth. One solar panel consists of 30 vacuum tubes with black exterior side and mirror surface internal side. There is a copper tube inside with circulating absorbent. The heat warms the absorbent. Collector transfers heat to the spirit and propylene glycol mix which in turn takes it to the accumulation tank.
Heating solution with solar panels can be connected with all heating methods. In Estonia it is possible to get 50 °C water and 712 kW energy with 1 m2 solar panel. Dimensions of one panel are 2.5 x 2.0 and absorbing surface is 2.93 m2. It is possible to receive 2068 kWh energy per year with one panel. Exact volume of energy depends on the location of the panel and building’s heating system. When solar energy is used for heating as well as heating domestic water, it is possible to use 60-75 % of available solar energy. Heating of pool water can use almost all available solar energy. Solar energy is accumulated to the accumulation tanks with different configuration. Configuration of accumulation tank depends on used heating system. We usually use Nado tanks with different volumes and components.
